What is the timestamp ?

Popular understanding is to prove the verifiable seal of time , For example, I want to take pictures , How to prove time , Beating the clock is obviously impossible to prove , We can prove it by shooting news newspapers and lottery numbers . Let's introduce the timestamp in detail ?

Time stamp means Greenwich mean time 1970 year 01 month 01 Japan 00 when 00 branch 00 second ( Beijing time. 1970 year 01 month 01 Japan 08 when 00 branch 00 second ) The total number of seconds since .

1. Self built timestamp ： This kind of timestamp is received through the time receiving device ( Such as GPS,CDMA, Beidou satellite ) To get the time stamp on the server , And issue the timestamp certificate through the timestamp server . This time stamp can be used to identify the internal responsibility of the enterprise , It has no legal effect at the time of court Certification . Because it may be tampered when receiving time through the time receiving device , Therefore, it cannot be used as a legal basis .

2. A legally valid timestamp ： It is a third-party trusted timestamp authentication service in China, which is built by the national time service center of Chinese Academy of Sciences and Beijing United trust Technology Service Co., Ltd . The national time service center is responsible for time service and punctuality monitoring . Because of its punctual monitoring function, the time in the timestamp certificate is guaranteed to be accurate and not tampered with . The platform for obtaining time stamp is “ Mass copyright protection platform ”[1] , It can be synchronized with the national time service center of Chinese Academy of Sciences .

Time stamp -> Standard time format

 

1. Back end transformation

for(int i=0;i<list.size();i++) {

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

//                 1- createTime   Creation time  2-  timeLastModified       Last modified  3-  cutPaymentTime  VIP Due date 

String dateString1 = simpleDateFormat.format(list.get(i).getCreateTime());

list.get(i).setCreateTime2(dateString1);

// 2.

String dateString2 = simpleDateFormat.format(list.get(i).getTimeLastModified());

list.get(i).setTimeLastModified2(dateString2);

// 3.

String dateString3 = simpleDateFormat.format(list.get(i).getCutPaymentTime());

list.get(i).setCutPaymentTime2(dateString3);

}

2. Front end transformation
